Abstract
The invention involves a process that reduces the potential for catalyst fluidization in a reduction vessel of a continuous catalyst regeneration system. The gas exit area from the catalyst reduction zone is increased by ventilating the cylindrical baffle of the upper reduction zone. This provides an increased exit cross-sectional area for the upper reduction gas to escape and reduce the overall exit velocity of the combined upper and lower reduction gases and reduces the potential for catalyst fluidization.
